import android.os.Bundle; 
import android.app.Activity; 
import android.app.Fragment; 
import android.support.v4.app.ActionBarDrawerToggle; 
import android.support.v4.widget.DrawerLayout; 
import android.support.v7.app.ActionBar; 
import android.support.v7.app.ActionBarActivity; 
import android.view.Menu; 
import android.view.MenuItem;

import android.widget.ArrayAdapter; 
import android.widget.ListView; 

public class MainActivity extends ActionBarActivity { 

    private String[] mPlanetTitles; 
    private DrawerLayout mDrawerLayout; 
    private ListView mDrawerList; 
    private ActionBarDrawerToggle mDrawerToggle; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     mPlanetTitles = new String[5]; 
     mPlanetTitles[0] = "Roma"; 
     mPlanetTitles[1] = "Milan"; 
     mPlanetTitles[2] = "TOTTI";

     mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
     mDrawerList = (ListView) findViewById(R.id.left_drawer); 

     mDrawerList.setAdapter(new ArrayAdapter<String>(this, 
       R.layout.drawer_list_item, mPlanetTitles)); 
     // mDrawerList.setOnItemLongClickListener(new DrawerItemClickListner()); 
     ActionBar action = getSupportActionBar(); 
     action.setDisplayHomeAsUpEnabled(true); 
     action.setHomeButtonEnabled(true); 

     mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, 
       R.drawable.ic_launcher, R.string.hello_world, 
       R.string.hello_world); 

     mDrawerLayout.setDrawerListener(mDrawerToggle); 

    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // TODO Auto-generated method stub 
     return true; 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.main, menu); 
     return true; 
    } 

}

Попробуйте это в вас активность: -

@Override 
     public boolean onOptionsItemSelected(
       MenuItem item) { 
      // The action bar home/up action should open or close the drawer. 
      // ActionBarDrawerToggle will take care of this. 

      /* 
      * if (mDrawerToggle.onOptionsItemSelected((MenuItem) item)) { return 
      * true; } 
      */ 
      // Handle action buttons 
      switch (item.getItemId()) { 

      case android.R.id.home: 
       if (mDrawerLayout.isDrawerOpen(mDrawerList)) { 
        mDrawerLayout.closeDrawer(mDrawerList); 
       } else { 
        mDrawerLayout.openDrawer(mDrawerList); 
       } 
       return true; 
     break; 

      default: 
       return true; 
      } 
      return super.onOptionsItemSelected(item); 

     } 

    /* The click listner for ListView in the navigation drawer */ 
     private class DrawerItemClickListener implements 
       ListView.OnItemClickListener { 
      @Override 
      public void onItemClick(AdapterView<?> parent, View view, int position, 
        long id) { 

       if (position == 1) { 

        mDrawerLayout.closeDrawer(mDrawerList); 
       } else if (position == 2) { 

        mDrawerLayout.closeDrawer(mDrawerList); 
       } 

      } 
     } 

     @Override 
     protected void onPostCreate(Bundle savedInstanceState) { 
      super.onPostCreate(savedInstanceState); 
      // Sync the toggle state after onRestoreInstanceState has occurred. 
      mDrawerToggle.syncState(); 
     } 

     @Override 
     public void onConfigurationChanged(Configuration newConfig) { 
      super.onConfigurationChanged(newConfig); 
      // Pass any configuration change to the drawer toggls 
      mDrawerToggle.onConfigurationChanged(newConfig); 
     }
